Very sad for Plymouth, and especially for the dedicated employees who've done their best for the last few years in the face of Sutton Harbour's determination to run the place into the ground. There's virtually nothing left - they made sure that the paying operators were pushed out several years ago. But that's what you get when property developers are given some prime city land on a plate. The company who decides whether the airport is viable or not SHOULD NOT be the same company who stands to profit in terms of millions from redevelopment of the same site if it closes, not when the site is owned by the City.
Best wishes to all at Plymouth.
